all on that side of the gut to which the mesentery was 
attached, and in which the blood-vessels ran; indeed, 
often they were quite close to these latter, although never 
actually in their walls. The infection was, in this instance, 
a comparatively limited one, and the functional activity 
of the intestine would be in no way interfered with—a 
very different state of affairs from that described above. 
There was no enlargement of the folds or pleats (con- 
sequently no occlusion of the lumen), and on opening, the 
internal surface (the mucosa) appeared quite normal. 
In size, the patches averaged about 1 mm., while the 
out-growths were sometimes 1}—2 mm. in length. Figs. 
2 and 3 shew some examples drawn natural size. In fig. 
2 there are three appendages (par) visible on one of the 
pyloric ceca, and close to the pyloric branch of the mesen- 
teric artery (art). In fig. 3 some more are seen, also 
mostly near the attachment of the mesenteric blood- 
vessels. 
Johnstone’s specimen and my own aptly illustrated, 
respectively, the two chief modi vivendi of the Glugee, viz., 
(a) cyst-formation, and (6) in the condition of “ diffuse 
infiltration,” ‘Thelohan’s (7) term for signifying an 
infected area in which the parasites and the tissue of 
the host completely intermingle. Fig. 4 represents a 
section of a portion of the wall of the intestine and an 
appendage under a very slight magnification, where the 
darker shaded part (par) shews the diffuse infiltration, 
and the hghter region is normal uninfected tissue. The 
out-growth, it will be seen, is practically entirely a para- 
sitic development, with the exception of a delicate 
covering of connective tissue and peritoneal epithelium, 
which is, in places, broken down (ep.). But, here also, at 
(cy.) an attempt at cyst-formation has taken place, really 
a pseudo-cyst, since in origin and nature these are very
